Bluetooth Identity Recognition via Local Mapping Table
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional Bluetooth (BT)-based identity recognition methods are insecure when the smart device loses network connection with the server, and they are inefficient due to the need for server-mediated ID determination, leading to potential communication insecurity and lower recognition efficiency.
Innovation Solution
A method and apparatus for BT-based identity recognition that allows a smart device to establish a BT connection with a terminal, acquire the user account, search a preset mapping table for the corresponding ID, and determine the user identity locally, even when not connected to the server, ensuring secure communication by pre-establishing mapping relationships between user accounts and IDs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the smart device uses server-mediated identity recognition, then the security of communication is improved, but the recognition efficiency deteriorates due to network dependency and additional communication overhead
Solution Approach 1:
The mapping relationship between user accounts and IDs is pre-established and stored in the smart device before actual communication occurs. When a terminal connects via Bluetooth, the smart device can immediately perform identity recognition by locally searching the pre-stored mapping table, eliminating the need for real-time server communication and thereby improving recognition efficiency while maintaining security
Solution Approach 2:
The patent introduces a local mapping table as an intermediary between the server and the identity recognition process. This mapping table stores the correspondence between user accounts and IDs, allowing the smart device to perform autonomous identity verification without continuous server mediation, thus resolving the contradiction between security (server-mediated) and efficiency (local processing)
2Reliability
If the smart device maintains continuous network connection with the server for identity recognition, then the security is improved, but the time consumption increases and recognition efficiency decreases
Solution Approach 1:
The mapping relationship data is preliminarily downloaded and stored in the smart device's local memory before it is needed for identity recognition. This allows the device to perform instant local lookups during Bluetooth connections without initiating network requests, thereby eliminating network latency and reducing identity recognition time while maintaining security through pre-validated mapping data

AI summary
A method for a smart device to perform Bluetooth (BT)-based identity recognition, includes: establishing a BT connection with a first terminal; acquiring a first user account of the first terminal through the BT connection; searching a first preset mapping table for a first identifier (ID) corresponding to the first user account, the first mapping table including a first mapping relationship between at least one user account and at least one ID, each ID corresponding to a respective user account, and the first mapping relationship being determined and sent to the smart device by a server; and determining a user identity corresponding to the first terminal according to the first ID.
